However, there exist beam range uncertainties that affect treatment efficiency. This problem can be resolved if the clinical beam could be monitored precisely in real-time, such as by imaging the prompt gamma emission from the target. In this study, we performed real-time detection and imaging of 718 keV prompt gamma emissions using a Si/CdTe Compton camera. We conducted experiments on graphite phantoms using clinical carbon ion beams of 290 MeV/u energy. Compton images were reconstructed using simple back-projection methods from the energy events of 718 keV prompt gamma emissions. The peak intensity position in reconstructed 718 keV prompt gamma images was few millimeters below the Bragg peak position. Moreover, the dual- and triple-energy window images for all positions of phantoms were not affected by scattered gammas, and their peak intensity positions were approximately similar to those observed in the reconstructed 718 keV prompt gamma images. In conclusion, the findings of the current study demonstrate the feasibility of using our Compton camera for real-time beam monitoring of carbon ion beams under clinical beam intensity.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"NATURE"}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.1038/s41598-021-00949-5","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://www.nature.com/articles/s41598-021-00949-5#citeas","subitem_relation_type_select":"URI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2045-2322","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Parajuli, Raj"}],"nameIdentifiers":[{"nameIdentifier":"1020689","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sakai, Makoto"}],"nameIdentifiers":[{"nameIdentifier":"1020690","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Arakawa, Kazuo"}],"nameIdentifiers":[{"nameIdentifier":"1020691","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kubota, Yoshiki"}],"nameIdentifiers":[{"nameIdentifier":"1020692","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kubo, Nobutero"}],"nameIdentifiers":[{"nameIdentifier":"1020693","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Tashiro, Matsumi"}],"nameIdentifiers":[{"nameIdentifier":"1020694","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Parajuli, Raj","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"1020695","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Carbon Range Verification with 718 keV Compton Imaging","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Carbon Range Verification with 718 keV Compton Imaging"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2021-11-05"},"publish_date":"2021-11-05","publish_status":"0","recid":"84571","relation_version_is_last":true,"title":["Carbon Range Verification with 718 keV Compton Imaging"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T18:20:25.843704+00:00"}
